Dr. Joel Oesch  - Plenary Bible Study Leader

Dr. Oesch holds a PhD from Concordia Seminary and is a graduate of Yale University. He is Director of the Graduate Programs in Theology. Professor Oesch served as Director of Christian Education for 10 years. His research interests are embodied theology, the writings of Dietrich Bonhoeffer, and contemporary culture. Joel is also the creator and Director of The Crosswise Institute of Concordia University Irvine which endeavors to engage high school students in meaningful dialogue on contemporary cultural issues that challenge their worldview and that calls them from comfort to something risky, but rewarding. Together, students are invited to develop their ideas, refine their thinking, and examine how the church community might respond to current and relevant topics as informed by Scripture. Ultimately, we want to bring these conversations to bear on the real lives of friends and neighbors as students go out with a thoughtful Christian perspective on current events, ethical concerns, and social trends. Joel has served Concordia since 2012.
